Artificial intelligence has been tremendously useful in science, but, most of the time, it is used for computational work, such as analysing data, making predictions and scouring literature. Carrying out ‘wet laboratory’ experiments — which involve handling liquids, biological material and chemicals — is another matter. An AI system might design a promising biologically active molecule in minutes, but testing it can take weeks or months and requires extensive human effort. In a paper published in Nature , Wu et al . 1 introduce AutoDNA, a lab in which AI agents plan and conduct molecular-biology experiments involving DNA, with relatively little human intervention.…
